[ovirt-users] Remove Vms with 200 GB Harddisk but gluster not Release diskspace

Hi Users, I have got a Problem: Vmstore is full with 97 % (3TB). I want to cleanup and have delete 2 vms with round 500 GB harddiskspace together on a single node. In gluster .shard/.remove_me are 6 files but after 6 h I got no new free diskspace. What I am doing wrong? Can I force the cleanup? I have ovirt 4.3.9 running. Br Marcel
